“What was being said was a red rag to a bull for the far right and others,” Khan told the BBC podcast, called "Why Do You Hate Me?"
“But what concerned me the most was if you're an innocent listener of this, because it's a secret undercover recording, in inverted commas, because it sounds like me, because of the timing and the context… And that's why it's so serious.”
Khan argued that organizations like watchdog the Electoral Commission need more powers to deal with misinformation.
“We almost had serious disorder,” he added.
The BBC says it traced the recording back to TikTok and what appears to be the originator of the clip, a profile called HJB News.
“I think parliament needs to wake up and understand that if they don’t take action, it’ll provide opportunities for mischief makers to be bolder,” Khan added. “I think it’s really important that we understand that the current laws we have around copyright, IP, criminal law aren’t fit for purpose.”
